Enter a URL
Want to know how often certain words appear in your content? Paste a URL (or your text, if the tool supports it) and this free checker will show you the most used words and phrases along with their density. It’s a quick way to see whether your writing looks natural or if you’re repeating the same terms too much.

Simple and fast — no account needed.
Keyword density is the percentage of times a specific word or phrase appears in your content compared to the total word count.
Example:
If an article has 1,000 words and the main keyword appears 12 times, the density is 1.2%.
In the past, some people tried to rank by stuffing the same keyword everywhere. That doesn’t work well anymore. Search engines generally prefer natural, useful writing. Still, checking density is helpful so you don’t accidentally overdo it or underuse important terms.
It helps you:
The goal is balance. Your content should sound like it was written for people first, while still clearly covering the topic.
There is no official “perfect” percentage from Google. Some SEO practitioners use a rough 1–2% range as a reference for a main keyword, but it should not be treated as a rule or target.
What matters more:
If the text sounds forced when you read it out loud, the keyword may be appearing too often.
Is this tool free?
Yes. You can use it without signing up.
Does higher keyword density mean better rankings?
No. Overusing keywords can make content difficult to read and may result in keyword stuffing. Natural usage is better.
Can I check any website?
Most public pages can be analyzed. Some sites may block automated tools or prevent external requests.
Is keyword density still important in 2026?
It is less important than creating useful, well-written content, but checking density can still help you identify excessive repetition and keep your writing natural.
What should I do if density is too high?
Rewrite some sentences, use relevant variations of the keyword, or remove unnecessary repetitions.
Note
Keyword density is only one small part of content quality. Useful, well-structured writing matters more than hitting any specific percentage.
